  • Patent number: 7800437
    Abstract: Methods and systems are disclosed for closed loop feedback for pulse width modulated (PWM) switching amplifiers using predictive feedback compensation (PFC) for suppressing distortions caused by supply voltage variations and output amplitude switching non-idealities in pulse width modulated (PWM) switching amplifiers by pre-compensating the PWM input based upon the supply voltage or output pulse amplitude and using closed loop timing feedback. Output amplitude errors associated with previous PWM output signals are used to predict output amplitude errors expected for future PWM output signals. These predicted output amplitude errors are then used to adjust the pulse widths for the future PWM output signals. Timing differences between pulse widths for the uncompensated PWM input signal and the pre-compensated PWM signal are used as feedback to provide closed loop width adjustment.

  • Patent number: 7737898
    Abstract: A line of sight antenna supported in an upturned terminal winglet or similar vertical member of an aircraft is disclosed. An aperture is formed in the conductive winglet or vertical member, and the antenna is supported within the aperture by a support mechanism such that the antenna is exposed to the line of sight transmissions. A non-conductive covering may also be used for the aperture. Using the cover, the antenna within the winglet can be configured so that it does not alter the appearance or aerodynamic characteristics of the aircraft. Alternatively, the antenna can be coupled to the outside of the winglet or vertical member if cosmetics are not a concern. The frequency range of the antenna can be tuned to cover desired frequency ranges. The antenna position at the winglet maintains a large physical separation from fuselage-mounted antennas thereby reducing interference.

  • Patent number: 7708325
    Abstract: Systems and methods for rotating objects that shift the center of gravity of an object, such as a wing assembly, from a position outside the rotation axis area of the object to a position within the rotation axis area of the object. In one example, a material handling system that employs rotatable slings may be used to rotate an object by shifting the suspended center of gravity from a position outside the rotation axis area (i.e., outside the rotatable slings in at least one position of rotation) to a position within the rotation axis area (i.e., between the slings at all positions of rotation). The suspended center of gravity may be shifted using at least one ballast component (or other suitable force-applying device) that exerts a force on the object in a direction and magnitude sufficient to so shift the suspended center of gravity of the object.
